Answer:
Step-by-step explanation:
1) IJ = 11cm ; IL = 4cm LK=?, JK=?
LK = 11 cm , JK = 4cm
2) m∠J = 68°, ∠L=? ∠I=? ∠K=?
m∠J = m∠L = 68°
m∠I = m∠K:
180 = m∠J + m∠I
m∠I = 180 - m∠J = 180 - 68 = 112°
m∠K = m∠I = 112°
3) IX = 4.5cm and LX= 6.5 cm
KX=?, IK=?, JX=?, JL=?
KX = IX = 4.5 cm
IK = IX + KX = (4.5) + (4.5) = 9 cm
or IK = 2(IX) = 2(KX) = 2(4.5) = 9cm
JX = LX = 6.5 cm
JL = LX + JX = 6.5 + 6.5 = 13 cm
or JL = 2(LX) = 2(JX) = 2(6.5) = 13 cm
4) Δ JIL ≅ Δ LKJ
Δ IJK ≅ Δ KLI
